Surgical management of gastric duplication cyst with respiratory epithelium in an asymptomatic child

Gastric duplication cyst (GDC) is a rare sub-type of enteric duplication cysts. Complete surgical excision is recommended due to potential risks of bleeding, perforation and malignant transformation. Our patient presented with an antenatally detected cystic structure posterior to the stomach. She was asymptomatic and kept on regular ultrasound surveillance, eventually undergoing open excision in early childhood. Histopathology confirmed a GDC with atypical finding of respiratory epithelium.
